rasta or rast

Among the Germanic peoples, at least as early as the first century –
16th century, a unit of itinerant distance, conceptually the distance
between "rests". It was introduced into present-day France by the Franks in the 5th
century. The Romans came to think of it as 3 mille
passus, (about 4.44 kilometers). In northern France and Belgium it was also thought of as 2 leuca.
In later maps it is described as “millare germanicum parvum,” the small German mile, equivalent to 3 of the then-current Italian
mille.
